While known to exist during the Revenge War, reports of them afterwards were considered largely anecdotal until a Unicorn was accidentally evolved into one in 76 AS.

Upon evolving, Nightmares become a solid black with crimson eyes and hair, including all body hair. They stand between 5 ft and 6 ft in height in their human form and are athletic in build, however they retain the figure they had while a Unicorn. While in their humanoid form, their enhanced speed is reduced to only four times human normal and they cannot fly. In their tauric form the tuft of their leonine tail and cloven hooves are also crimson. They also grow in size and no Nightmare has been documented as being less than 15 hands (5 feet) at the equine shoulder. No matter their size, all tauric Nightmares are built like thoroughbreds and are very agile and quick. While tauric, Nightmares can fly by the simple expedient of galloping on the air. They can turn and maneuver as they could on the ground, making them very agile, but still somewhat poor combatants against other flying pokégirls who can climb and dive much more easily.

In either form the Nightmare has the ability to instantly create a chitinous armor that covers her entire body, moves with her and does not impede her in any way. This armor is covered by tiny points that are razor sharp and will injure any unarmored opponent who contacts them. In battle, Nightmares often use this with Double Edge to leave their opponents a bleeding mess.

During the Revenge War, Nightmares were used as fast strikers both on the front lines and in assaults on strategic rear targets and supply lines. With their ability to fly fast at very low altitudes and their use of phase to avoid terrain obstacles and walls, they could go almost anywhere without the fear of being intercepted. Those abilities translate well into Pokégirl combat and today the Nightmare fills almost the same role in Pokégirl battles, maneuvering quickly to outflank her opponent and then hitting her hard with a series of attacks that pulverizes her.

Nightmares are strong individualists with a serious personality and are always planning the best ways to complete their objectives. They feel they are well suited to being alpha, although in most cases their almost complete focus on themselves means they are terrible at it. Still, they will maneuver to gain their Tamer’s favor and become the alpha whenever possible. To this end, Nightmares will adopt the sexual fetishes of their Tamer as their own. It is unknown if they have a personal preference since they always say that whatever their Tamer likes is their favorite position and/or technique.

Feral Nightmares are always encountered in their tauric form. Even though they lose the Unicorn’s ability to block Pokéballs, feral Nightmares are hard to capture because they remain aware enough to phase before a Pokéball can strike them and with their speed a Tamer seldom gets two chances. In almost every capture, the Nightmare had to be rendered unconscious before she could be caught.

There is no record of a human thresholding into a Nightmare.
